Front

What is salivary amylase?

Back

Salivary amylase is an enzyme produced in the saliva that breaks down starches into sugars, aiding in the digestion of carbohydrates.

Front

What would humans have difficulty digesting without salivary amylase?

Back

Humans would have difficulty digesting carbohydrates without salivary amylase.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, essential for maintaining life on Earth.

Front

What must happen for the carbon cycle to continue in a closed terrarium?

Back

All organisms must continue to exchange gases.

Front

What is active transport?

Back

Active transport is the process of moving substances across a cell membrane against their concentration gradient, requiring energy, usually in the form of ATP.

Front

What is the best evidence that a cell is using active transport?

Back

ATP is being rapidly consumed near the cellular membrane.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving from high to low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the function of the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions in photosynthesis that produces sugar from carbon dioxide.

Front

What does ATP stand for?

Back

ATP stands for adenosine triphosphate, which is the energy currency of the cell.
